A boat weighs 57600 lb. Its propellor produces a constant thrust of 36000 lb and the water exerts a resistive force with magnitude proportional to the speed, with 1800 lb-s/ft. Assuming that the boat starts from rest, find its velocity as a function of time, and find its terminal velocity. v(t) = Terminal Velocity =
